Energy Efficiency in the 2019 IRP
EE in IRP Rule Description of demand-side resources
o Energy efficiency and load management Expected capacity and energy impacts Explanation of impact on PNM’s load forecast Include DSM on PNM loads and resources table
Load Forecast Impact One of many factors affecting future energy use EE impact is growing due to cumulative nature of savings
o Measures continue to save year after year Program funding is significant – $24.8M in 2019 Program savings = decrement to the PNM load forecast
Energy Efficiency Definitions
• Conservation• Using less energy
• Ex: Higher/lower temps• Energy Efficiency (EE)
• Using less energy but keeping the same or better level of service• Ex: replace incandescent with LED
• Load Management (LM)• Actions that reduce peak demand or shift demand to off-peak
• Ex: Ice storage – off-peak cooling • Demand Response (DR)
• A type of load management – utility control of load• Ex: PNM Power Saver
• Demand Side Management (DSM)• Term that covers all of the above
Energy Efficiency Definitions
Addressed in EE ForecastPNM EE Programs Incentives cause faster uptake
o Ex: Rebates on LED bulbs
Free Rider Savings Form of naturally occurring Participant in utility program that would have bought the
equipment even without the incentive Reported savings = net of estimated free rider savings
Energy Efficiency Definitions
Addressed in Load ForecastNaturally Occurring EE
Natural productivity improvements – implicit in forecasto Ex: Upgrading equipment, home and business
Persistence Also referred to as Market Transformation, as well as Codes &
Standards. What happens to the savings of a measure after the effective useful life (EUL) of a measure expires.
Codes and Standards State building codes
o Ex: NM code = 2009 IECC Federal appliance standards
o Ex: Minimum SEER ratings

Enabling Legislation – Efficient Use of Energy Act (EUEA)
• Enacted 2005 – amended in 2008 & 2019• Requires utilities to offer cost-effective programs
o Benefits must be greater than costso Utility Cost Test (benefit/cost ratio)
• Independent verification of savingso PRC selected evaluator
• EE funding = 3-5% of retail revenues starting 2021• Energy savings goals
o 5% of 2020 retail sales by 2026 (5 years 2021 thru 2025)• Solicit input from interested parties
o PNM EE public advisory group• Costs recovered through rate rider
o PNM Rider 16

• Load reduction capacity is “dispatched” by PNM system operators
• Utilized on hot summer days to help relieve system peak demand
• 3 “events” in 2019 with average capacity of 48.5 MW
• Currently, about 46,100 customers participate

Energy Efficiency Forecast Assumptions
Factors Impacting EE Forecast1. Total Portfolio Funding Forecast2. Program Mix Projections3. Program Cost Assumptions – $/kWh Saved
Other AssumptionsEE Usage Profiles Converts annual savings to hourly
Customer Participation Assumed to continue participating as long as programs are
attractive
Energy Efficiency Forecast Assumptions
Total Portfolio Funding Assumptions1. Forecast period aligned with IRP: 2019 – 20392. Funding level as defined by EUEA 3-5% of retail revenues continues through forecast
period3. Projected 2020 funding based on latest EE/LM Plan filing Filed April 2016 Based on approval of rates as filed in Case 15-00261-UT Proposed budget = $28M Actual budget to be adjusted per Final Order
4. Future EE/LM funding Annual funding escalates at ½% beginning 2019
Energy Efficiency Forecast Assumptions2017 IRP values, new forecast coming soon
Energy Efficiency Forecast Assumptions
Program Mix Assumptions1. Existing EE programs Individual forecasts over near term (4 to 6 years) Effective useful life varies by program (historical average = 9 yr.)
2. Future EE programs Generic – 50/50 split between residential/commercial
programs Forecast increased to match the EUEA goals by 2025
3. Load management programs (DR) Individual programs forecasted through planning period
Energy Efficiency Forecast Assumptions
Program Cost Assumptions1. Program incentives and costs are increasing Ratio of program cost per kWh saved is increasing 2013 ($0.136/kWh) vs. 2018 ($.248/kWh) average escalation
rate = 13%/yr. Note: Costs were flat between 2017 and 2018
2. Base case escalation assumption – $/kWh saved 4% beginning 2019
3. Higher savings sensitivity assumption 2% escalation rate beginning in 2019 Lower escalation = more savings at given budget
